IVILLIAM Il. TURNBULL, OF DEFIANOE, OHIO.

WASHING- MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 453,135, dated May 26,1891.

Application filed March 13, 1890. Serial No. 343,742. (No model.)

To all whom it may concern,.- Beit known that I, WILLIAM H. TUENBULL, ofDefiance, in the county of Defiance and State of Ohio, have inventedcertain new and useful Improvements in IVashing-llachines; and I dohereby declare the following to be a f ull, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit pertains to make and use the same.

My invention relates to improvements in washing-machines; and itconsists in certain features of construction and in combination of partshereinafter described, and pointed out in the claim.

In the accompanying` drawings, Figure l is a side elevation in section.Fig. 2 is a plan. Fig. 3 is an elevation in detail taken at right anglesto the view shown in Fig. l.

A represents the tub or vat, the same being constructed of fibrous pulpmolded into approximately the form shown, the bottom member A thereofbeing concaved and provided with a central opening for receivingdraincock B, by which arrangement the tub is readily drained. On theinside of the tub. the bottom member A is corrugated-for instance, asshown in dotted lines a', Fig. 2. Also, alternate sections of the sidewall A are corrugated vertically, as shown ata ce, these corrugatedsections alternating with smooth sections a2, the corrugations of boththe bottom and side walls being constructed in molding the tub. The topwall A2 of the tub has a large opening for receiving cover O, cleats A3being secured to theunder side of wall A2 at least on two sides of theopening, these cleats projecting toward each other, as shown in Fig. l,for supporting the cover. The cover may be hinged to wall A2, or thecover and attachment may be lifted bodily from the tub in gaining accessto the inside of the tub.

D is a cast-metal plate, preferably integral with standard E. Plate Dhas a depending hollow hub D', that externally ts in a correspondingseat or depression in cover C. Plate D has depending lugs d, that extendthrough corresponding holes in the cover, these lugs having lateralholes adapted to receive keys d belowthe cover for securing the platerigidly to the cover.

F is the driving-pinion, the same having a hub j'. The depending sectionof this hub is journaled in the counterbore or enlarged chamber of hub Daforesaid. The pinion and hub are provided with a tapering verticalsocket for receiving the corresponding upper section of wooden stem G. Abolt gis set into and projects from the upper end of Stem G, this boltextending through a corresponding hole in the upper end wall of hub fand the bolt extending also through a vertical hole in yoke H, the boltfitting loosely in this hole. The feet of this yoke rest on plate D, towhich the yoke is secured preferably by means of screws shown at h.

On stem G is mounted a wooden disk or head I, the latter having acentrally-located hole adapted to iit stem G loosely, so that head I mayslide up and down the stem, the latter being provided with a lateralhole near the lower end thereof for receiving pin G for holding the headon the stem. IIead I is provided with a series of pegs t', substantiallyas shown, these pegs engaging the clothes and serving as beaters inwashing.

Standard E has a hub E of considerable length and located midway 'of thestandard, and in the bore of this hub is j ournaled crankshaft e, thelatter being provided at the outer end with a hand-crank c and providedat the inner end with a shorter crank e2.

To the upper end of the standard, at E2, is pivoted the depending arm J.This arm terminates below in a segmental gear J', the teeth of which areadapted to engage the teeth of pinion F aforesaid. Arm J has alongitudinal slot j, in which slot operates the wrist of. crank c2. Byturning crank c arm J is oscillated, whereby pinion F and attachmentsare rotated alternately in opposite directions. Plate D is provided witha lug or rub-iron at cl2, that by bearing against the rear side of thesegmental rack holds thelattcr to its engagement with thedriving-pinion.

The construction of the/side walls of the tub, comprising, as aforesaid,alternate smooth and corrugated sections, is found to be very effectivein washing. Also, the concaved bottom of the tub allows the heavier dirtto gravitate to the center thereof, where it remains practically out ofthe way of the clothes in rubbing the latter on the corrugated sectionsof the bottom and of the sides. 'llle corrugationsboth of thebottom andside walls of the tub being molded iu are much superior to any ribs orother mechanism that may take the place of such corrngations, where suchribs or other devices have to be fastened to the tub. l

That I claim is- The combination, with a tub and a cover, of a platesecured to the cover, a standard rigid with the plate, a swinging armdepending from the upper end of the standard, a crank carried bythestandard for rocking the depending arm,a segmental gear on ille lowerend o the swinging; arm, a pinion mounted on the plate and en gagging'the segmental gear, anda stem secured to the pinion, substantially asset forth.

In testimony whereof I sign this specica tion, in the presence of twowitnesses this 5th 2o day of February, 1890.
